Chaincode
Chaincode is the term used in Hyperledger Fabric to refer to the business logic or smart contracts that run on a blockchain network. It defines the rules and data structures for transactions, enabling the manipulation of ledger state.
Architecture & Execution
- Runs in isolated execution environments (e.g., docker containers or WebAssembly modules).
- Invoked by Transactions via a Proposal flow: clients submit proposals to endorsing peers, which simulate the chaincode to read/write sets without committing to the ledger.
- Supports multiple languages, primarily Go, nodejs, and Java.
Key Characteristics
- State Management: Maintains a key-value store for the specific chaincode instance.
- Isolation: Each chaincode instance operates in its own namespace to prevent conflicts.
- Lifecycle: Managed through a lifecycle proto
